Each mailing list is a list of subscribers, i.e. a list of E-mail addresses receiving messages posted on the mailing list.
In order to subscribe, unsubscribe, and change their subscription mode via E-mail, users of the listname@domain mailing list should send any message to the following addresses:
|Send to address:||New USer||Existing subscriber|
|listname-on@domain or listname-subscribe@domain||to subscribe to the list in the default mode||to confirm the current subscription mode|
|listname-feed@domain||to subscribe to the list in the FEED mode||to change the subscription mode to FEED|
|listname-digest@domain||to subscribe to the list in the DIGEST mode||to change the subscription to DIGEST|
|listname-index@domain||to subscribe to the list in the INDEX mode||to change the subscription mode to INDEX|
|listname-null@domain||to subscribe to the list in the NULL mode||to change the subscription mode to NULL|
|listname-off@domain or listname-unsubscribe@domain||to unscribe from the list|
|listname-confirm@domain||to get the confirmation ID; this ID can be used as the password for other subscription operations and for list archive browsing|
When subscription request messages are sent to these addresses, the message From: header fields are used as requesters E-mail addresses.

moderated: all subscription requests will be stored in the listname/requests Mailbox (see below) and should be approved by the list owner. The List owner should redirect these requests to the listname-on, listname-feed and other addresses to subscribe new users and to let them change the subscription mode. Users still can unsubscribe by themselves. When user requests are stored in the listname/requests Mailbox for approval, they are "flagged" (get the Flag marker).
